unraided

unMENU did the trick, Thanks for your help.

Hi, I should of mentioned I'm not using unmenu, I was hoping in using Postfix natively, but if nothing provails, it might be my only option. Thanks

I've been using the following Postfix install for other Linux machines I have, http://notepad2.blogspot.com.au/2012/04/configure-postfix-to-send-emails-via.html to email me a health report of my disks SMART events to alert me if a disk is dead/dying. I cannot seem to find a postfix*.tgz package I can use to install for Slackware, which in turn, can't get it to run on unRAID. Has anyone explored Postfix for unRAID or know of a solution? PS: I've looked at sSMTP, it's buggy, I haven't been able to get any success from it, even under a Slackware-based distro. It keeps failing at authenticating with GMail saying TLS isn't started whhen in fact it has TLS enabled. Thanks

The server, in my case will power on the morning, just before 6am, on selected days to do a rsync, just after 6am, to another server, hence why I use at, you could use cron to schedule it better I guess.

I've always wanted to create a easy, well, lazier way to monitor SMART reports. I've constructed a script to execute every morning using at via the go file, reporting on the overall health of all my attached disks, echo "Current status for /dev/sdb" > /mnt/user/share/_Logs/_smartctl/smartctl_20`date +%y%m%d`.log smartctl -H /dev/sdb |grep "SMART overall-health self-assessment test result" >> /mnt/user/share/_Logs/_smartctl/smartctl_20`date +%y%m%d`.log echo "" >> /mnt/user/share/_Logs/_smartctl/smartctl_20`date +%y%m%d`.log echo "Current status for /dev/sdc" >> /mnt/user/share/_Logs/_smartctl/smartctl_20`date +%y%m%d`.log smartctl -H /dev/sdc |grep "SMART overall-health self-assessment test result" >> /mnt/user/share/_Logs/_smartctl/smartctl_20`date +%y%m%d`.log echo "" >> /mnt/user/share/_Logs/_smartctl/smartctl_20`date +%y%m%d`.log echo "Current status for /dev/sdd" >> /mnt/user/share/_Logs/_smartctl/smartctl_20`date +%y%m%d`.log smartctl -H /dev/sdd |grep "SMART overall-health self-assessment test result" >> /mnt/user/share/_Logs/_smartctl/smartctl_20`date +%y%m%d`.log echo "" >> /mnt/user/share/_Logs/_smartctl/smartctl_20`date +%y%m%d`.log " " " which produces the following output Current status for /dev/sdb SMART overall-health self-assessment test result: PASSED Current status for /dev/sdc SMART overall-health self-assessment test result: PASSED Current status for /dev/sdd SMART overall-health self-assessment test result: PASSED " " " You can write this log to the path where unRAID keeps the syslogs (/boot/logs), but I placed it to a directory on my main share for easy reading on a client machine. I have no doubt their many other, albeit better ways to do this via some addon or something or other, I haven't been keeping up to date with v5.0, but this IMO is a convenient way to know if the disk(s) are on the blink without creating a terminal session to your box and examine the syslogs, using a addon if you choose not to, log onto the web interface, etc... Of course, if a disk fails, you'll probably know about it when you look for something and notice it's missing Cheers

Is is possible to customise the bzroot image file to include additional packages/binaries or other files without having to use the go file to install or include them? I've got some Slackware packages and bits and pieces and was interested to have these built in. Thanks

I've got a Asus MB, no HPA, and plan to the the final 4.7 release. I'll make a backup, usually by renaming the existing bzroot and bzimage files, along with the config folder too. Fingers crossed. Thanks bgp999, Joe L and Orbi.

Thanks for the tips. I know upgrading for 4.4.x to 4.5 was easy and I normally backup the previous bzimage and bzroot files as a precaution. Cheers

I've been running 4.5.1 Pro for over a year now and noticed 4.7 is out. I've been out of the unRAID loop for a while and know a lot changes with features, support, etc... with newer releases. Will upgrading to 4.7 on my current version pose any issues with my existing disks, data or any other disks I plan to add in the future? The server originally built with 4.4.2 Pro, and was progressively updated to 4.5.1 when updates where available. I have iStat Server as a addon. Thanks.

What is the name of this app that you've used to test the read/write speeds? Cheers

I only have one word to comment on this set up, Awesome! Man you can never have too much data. I take it you don not run these guys 24/7?

I believe you can, having said that, you'd want to remove all currently attached disks from your unRAID server BEFORE running a Stress test using StressLinux! It'll allow you to run tests on most componemts on your server, including disks, which it might need to read/write data to your disks too, potentially destroying your unRAID array to the point of no return! To be on the safe side, if you plan to boot into StressLinux, download the latest ISO from their site "http://www.stresslinux.org/sl/", use MultiBootISOs utilitiy "http://www.pendrivelinux.com/yumi-multiboot-usb-creator/" and create a bootable USB drive to boot from the downloaded StressLinux ISO, detach all of your currently attached unRAID disks, and attached a few old disks which you don't care about loosing any data from, boot from your newly created USB drive, run StressLinux and test all attached hardware components to see what (or hopefully) fails to pin point the defective hardware component. You can use MultiBootISOs to apend or create another bootable USB drive to test Ubuntu as well. Given it is a full OS, it'll try to initialize all hardware components it detects (You'll hopefully see this whislt it booting up/pre GUI) and if it tries to load a driver for part XYZ and fails, crashes, etc... other then loading the driver normally, you'll then know what the dud component is. I can't guarantee it will sus out the fault component, but worth a try. If Ubuntu starts sucessfully, try creating a Samba server and share all individual disks, and write some large files to each one and see it this causes it to fail too. You could finally recrete another unRAID server from a spare USB drive (unlicensed edition), install three spare disks, build a test server and see if that crashes too. If it doesn't, it could be a dud or corrupt file on your existing unRAID USB drive or the USB drive itself is a dud. Hope the above helps, Cheers

Have you tried to boot a Linux distro on this server (Like Ubuntu on a USB drive or something like that) and see whether it crashes? In theory, if you tried this test, Ubuntu should mount all disks as individual disks, thus allowing you to set a make-shift Samba file server, and then write a large file to each disk via an individual disk share as a test. You could get the server to boot into StressLinux, which does a full HW stress test (Be careful as it might do a disk test, resulting to data lost, so be careful!), it might be a faulty disk controller or other component besides the RAM? I've seem bad RAM cause Kernel Panic erros and the alike, other failing hardware can cause the same error. Hope this heaps, Cheers.

Well, not that this is helpful, but the problem looks like a network issue at 1636:42. You said you were able to telnet in, so you didn't lose all connectivity to the box... - Correct. I was able to connect to it, but it was like it was on a very slow dialup connection. I was able to visually see the HTTP site, but it didn't render very well and the shares were not viable, Windows Explorer kept crashing while attempting. Any other problems at that time? Mini-power-outage? Trouble with NICs? - Na the power hadn't gone out, the NIC's seem to be fine all round and is all fine today. Bouncing the server fixed the issue though, perhaps a buffer overload on the NIC for my unRAID server? I would say this kind of event would of been recorded in my syslog?The connection on the NIC (cable) is firm as well. Cheers

Hi. Today I was streaming a SD video from my unRAID, and it stopped responding, basically the network file share and the HTTP site was very unresponsive. This same result occurred on another PC (Both Windows 7 x64 systems). I was able to telnet to the box and restarted it, which fixed the issue and the unRAID performed fine. I've attached my latest syslog file. I can't ascertain why this occurred, though the same/similar instance may of happened some time ago, though I can't exactly recall. I'm on unRAID Server Pro v4.5.1. My server is built from 10 Seagate 1.5TB 7200RPM disks, using the 6 on board SATA ports on a Asus M4A785T-M mobo, and the remaining 4 disks are evenly running off two SiliconImage 3114 SATA PCI cards. The temperature of the disks were at 40C and are set to switch off after 3 hours of inactivity (Though the sever was only running for 2 hours when this incident occurred). Any reason what can cause this or why this happened? Cheers syslog-20110409-164514.zip

I was under the impression that 25MB/s was OK too? Interesting I read this thread, I've noticed that I use to average 16~23MB/s, and sometimes above this write speed, but it's dropped to 10~12MB/s recently, so I need to do some testing as to why it has dropped from me . As you know, unRAID isn't built for speed, but rather more for redundancy. In a situation where the unRAID array is always protected (not using a cache drive) and you're using good hardware (mobo/disks/LAN devices), the I/O internally and externally to and from the server should be acceptable for home use. Most unRAID users use their servers for media streaming or as a personal backup solution. Reading from an unRAID box should result in 90~100 MB/s at best, I presume. Wanting anything about 25MB/s write speeds using a fully protected setup, you could forgo unRAID for another NAS solution (FreeNAS/OpenSolaris server and use a ZFS array), or buy a 3rd party product. Remember though, you'll be trading off speed VS redundancy, which no other RAID solution offer like unRAID does. Using a cache drive in your server is good for a speed boost, but what if the cache drive fails not long after you've written several gig's worth of data to it, without having the chance to write the cached data to disk and parity? You need to question where you can sacrifice this risk for speed, and whether you can recover from this possible situation? Fair enough if this isn't such an issue for you in the instance that you loose your cache drive and you can recover this data, but if you have the tendancy to move your data from source to destination, that singe move of data getting lost on a faulty cache drive could be a problem one day. Another way to vastly improve write speeds, if you needed to transfer several hundred of gig's worth of data or anything greater then a TB, you can directly attached your source drive (Being an external HDD using USB2/eSATA or even a SATA or other hard drive) to your server, mount the disk and use a cp commed to move your data internally, bypassing the LAN and client altogether. Even in a standard unRAID setup with no cache drive, you'll be achieving far greater writes speeds in a DAS fashion, rather than a disk to LAN to disk bottleneck. Just a few things to take in. I'm an unRAID fan and use it for redundancy, not for speed. Cheers

Like the fact you used the CF cards, nice.

Like what Spectrum quoted, user accounts are the way around this, to place access rights on a per-share setup. You could, have your movies grouped in one share, and leave this share for movies to be read access to all users (not requiring a user account), and if you've grouped other disks for private data, create a user account and set the permissions for this share, so only a specific user account locally created on your unRAID can access this share. If a share access permissions assigned to it locally, Windows will prompt you for a user name and password, simply enter the credentials and it'll validate your access. Cheers

It's like the CM590 again, a really good case, crippled by those stupid 5.25 dividers! I think Lian Li are few of the only case manufactures that build cases without the dividers, allowing the 5-3 disk caddy's to be installed.

Basically, if you see such an option as Joe L mentioned (as it is known as different names), if you see it enabled in your BIOS for your Gigabyte mobo, just disable it. Having said this, a firmware/BIOS update may have rectified this issue. One of my Gigabyte mobo's originally had this feature ENABLED, but the BIOS update has since DISABLED it as a default function, so if your CMOS battery died, you're still safe, unless you manually go and enable it! As a safety precaution, I originally bought a Gigabyte mobo for my first unRAID server, and in fear, replaced it with a ASUS board. The original board I've now used it for a Windows desktop, and had then I later updated the BIOS, disabling this feature. With installing a disk into unRAID, the simple process is unRAID detects the new drive, though you have to add it as part of the array, unRAID will automatically format and prepare the disk. Please read the link below to answer most of your uncertainties regarding unRAID: http://www.lime-technology.com/wiki/index.php?title=UnRAID_Manual Better still, use a virtualised version of unRAID which I whipped up, perfect for newbies or for testing: http://lime-technology.com/forum/index.php?topic=6260.0 Hope the above helps Cheers.

I'll try and review your suggested parts list first: 20 2TB Hard drives $100 each or $2,000 - Good if you need all this storage ATM. What brand or brands are you considering? I'll let the guys will comment on what brands are the best buy ATM. Depending on your geographical location, 2TB should be good, cost wise. 4 4GB sticks of corsair ram - $160 - Do you mean 4x4GB RAM? if so, an overkill, just 4GB of RAM is plenty, but that's my opinion. Andtec Twelve hundred case - $200 - Good. Power supply (to be determined) $50-$10o - Get something like a 600W+, some forum members can direct you to something more specific. 880GMA motherboard (Free!) - OK, but be wary of Gigabyte mobo's copying or dumping the BIOS config locally to a disk, causing problems, so be sure to DISABLEW such options in BIOS or update to the latest firmware revision! 24 port sas card - $400 with shipping - OK, again, I let some of the guys suggest more specific models and types. the 5.25 to 5 3.5" bay converters Newegg.com - SNT SNT-SAC3051TL 5 x 3.5" HDD in 3 x 5.25" Bay SAS/SATA Trayless Backplane Hot Swap RAID Cage $75 dollars each, I'll need four of them. $300 - OK. 12 4 pin molex connectors for the power for the drives. - Depending on the P/Supply, you might get them included. 30GB SSD $?Huh?? Might buy this new or second hand, don't know how much it will cost so far. - For cache drive, OK, though I'd wait for some feedback from the guys. H50 Cooler for the heck of it Tongue -$70 (will get on sale for about 50) - OK. AMD Sempron 145 Processor 2.8GHz - $50 - Good enough unRAID isn't CPU intensive. UPS in case of a power outage, - $160 on sale (or I'll get a cheaper one but this could power my file server, my hdtv and my moms computer Smiley - The way to go for sure, good. The guys will comment on a specific model. 2 120mm fans. - Good. Regarding unRAID and data lost, like anything, if you're not certain about when something goes wrong, search and read the forums FIRST! it is certain that what your encountering, someone else has encountered the same problem. Their was a known bug with a version of unRAID (v4.5.3), which had caused some data lost to some, and was rectified by a later update, but the golden rule, if your current revision is working, stick with it and let others report on any problems before you upgrade, try not to be too bleeding edge with updates. unRAID has a unique RAID facility, meaning if multiple drive lose occurs, you can still retrieve your remaining data on the others drives, where as other RAID solutions can't offer this. Well I hope the above reassures your worries. unRAID is a great product, I've used it for year and a half, hasn't given me too much issues and anything I faced, someone else I faced it too and was easily rectified. The forum is excellent and has always helped when I needed it. Cheers

Hi all. After reading about Tapatalk, I decided to get this app for my Nokia N8 running Symbian S^3. What a winded and a obscure task it has been, and it still doesn't work properly. I originally referred to the Tapatalk site, too which it allows you to download a 'so called' install file to retrieve and install on the fly, called 'tapatalk.dm', that doesn't work and only allows me to open the file as if it was a text file. Then below that link provides a link to the Nokia Ovi Store, which gives me (on all attempts) that this is unavailable to download, still can't get the app! Then finally asking Mr Google where I can download a install file compatible for the Symbian S^3 OS, sucess, I was able to download a install widget-based application. Another problem... The app seems very slow at doing anything, from searching for available forums, to signing in, etc... by which (in most instances) I only get a blank screen as a result. Ok, so I uninstalled and reinstalled another copy which i retrieved from another source, the same problem... Finally, I thought it might of been my 3G connection to blame (seeing that this app is constantly seeking and talking to the net), I tried placing the phone in offline mode and leveraging off my WiFi connection, again, the same results with the way the app performs and all other web-based applications, ie: Web Browser and the alike work fine on all connections during testing Tapatalk. My question is, is their anyone who has encountered the same issues I mentioned above or has your Tapatalk experience for your Nokia been OK? This seems like a cool app, but it's been a hassle to get what seems simple to work on my phone. I don't have another Symbian S^3 phone to test this out on. Cheers.

It will have a red dot until it is completely rebuilt I think. As you're probably experiencing, it'll take a while to finish, too which if all goes well, the disk will be in a green state. Hope this heaps.

Have you tried going into the CLI and then typing passwd root You should then be able to change the root password. To telnet to your server, even if you had a blank password, by which the password was nothing/no characters, you'll still be prompted to enter a password, which you just press 'Enter' and the session will accept your login request. Your shares can be modified to use a different user access, which don't have to have password set, or even configure you're shares to not be authenticated by a local user account residing on your unRAID server. Hope this helps.

I'm an unRAID user and love the flexibility of it and the main reason I went with it was the fact that if I ever were to loose several disks, I can still retrieve the existing data on the working disks or in fact if unRAID was no more, you can mount the reiserfs with another distro or using a Windows GUI tool to extract and copy your data from it. In most other disk array solutions, this is not possible, leaving you with nothing. But where credit owed is were credit is due with ZFS. In fact, you can expand a ZFS array, mainly referred to as a 'pool' by adding additional disks, but you cannot decrease the number of disks within the pool, and you must then maintain that same number of disks for the life of the pool. The only way to do decrease the disks capacity this is to copy your data off the server, destroy the pool and recreate it (Annoying!). ZFS has the ability of losing one disk, whilst maintaining the data in a RAIDZ1 configuration (like a RAID5) and the ability to loose two disks in a RAIDZ2 pool configuration (like a RAID6). Other advantages in ZFS is good write speeds, snapshot clones which is a handy way to restore the FS from a previous point in time and the prevention of bit-rot (Though the later is rare). You can expand a pool by keeping the same amount of disks, but you'll have to replace each disk in a 'one-by-one' fashion, with the same size, let the pool resilver (heal and rebuild internally) and then the pool will only increase then, once you have fully replaced all disks of the same kind, and not while you have a mixture of different sized disks (A down fall for ZFS too). Obviously unRAID doesn't suffer from that draw back and is fair more flexible in that right. Another bonus to having a FreeNAS and a ZFS build is that it is a lot faster then unRAID. FreeNAS has the ability to aggregate multiple NIC's for redundancy or performance gains, where unRAID doesn't. But all in all, for home use, the last point isn't such a problem, as you would tend to probably use FreeNAS for for business use for its particular feature set that it provides and unRAID for home use for the way it works and functions. Again, I favour unRAID for redundancy by the way the RAID array functions, which to me is my primary concern, but its good to know the facts of both products as well.
